Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 755 AM EDT Sun May 28 2017 Valid 00Z Mon May 29 2017 - 00Z Mon Jun 05 2017 Latest guidance is fairly agreeable and consistent for the upcoming week's surface forecast. Initially weak nature of the east-west ridge along 30N latitude will lead to light trade flow through Monday and a greater than average land/sea breeze focus for shower activity. Subsequent strengthening of the ridge will bring trades back to moderate-brisk levels from Tuesday through the rest of the week. High pressure will begin to retreat northeastward late in the week but models/ensembles agree that it may take until next weekend for trades to weaken a little. With the stronger trade flow expect a return to generally windward focused rainfall, but with amounts tending to be in the lighter half of the spectrum as precipitable water values remain within a standard deviation either side of normal. A shortwave aloft currently crossing the islands may promote isolated rainfall enhancement early in the forecast period. Compared to yesterday guidance is more agreeable regarding how quickly the feature departs to the east, clustering more closely to yesterday's GFS/GEFS/UKMET that were in the slower group of solutions.
